This thesis addresses the interconnectedness of environmental sustainability and economic sustainability. There is evidence from the Canadian experience that market economies are extremely dependent upon consumption - the most significant factor in determining the overall level of economic activity and economic growth. Therefore, from this perspective, several periods of declining consumption would create a ‘vicious cycle’ [Kaldor, 1967] of economic decline that would be politically unsustainable. The analysis here shows that income inequality drives changes in debt-fueled consumption, and consequently, debt influences consumption. The role of income inequality as a mediating channel of sustainability via the borrowing/lending model presents evidence that ‘conventional’ debt servicing behaviour in the macro-economy can support steady-state economic growth that is, in economic terms, sustainable. Solving the conflict between the environment and the economy lies in private and public investments in new technologies and, most importantly, new social institutions that facilitate economic, political, and environmental, sustainability.

Least cost path analysis is considered by many scholars as being a good proxy for studying movement and interactions between sites in the landscape. Although it is widely used, there are many limitations and challenges yet to be overcome concerning the reliability of the results. The examples used from the Göksu Valley during the late Roman Imperial rule emphasize the need to clearly understand how the tool works in generating least cost paths and how these can be interpreted and related to human movement. The resolution and accuracy of the elevation data used also play an important role in least cost path analysis and these depend on the topographical area being studied. New venues are constantly being sought and the success of any analysis depends on how the results are compared and tested in concert with data obtained from various sources and through more visually advanced mapping software.

Parody has been a strategy within cultural production since the ancient Greeks: “paraodia” referred to a song sung alongside the main narrative thread of a dramatic work; the prefix “para-” also signifies “against.” In A Theory of Parody: The Teachings of Twentieth-century Art Forms, Linda Hutcheon offers this core definition: parody is “a form of repetition with ironic critical distance, marking difference rather than similarity … [with] tension between the potentially conservative effect of repetition and the potentially revolutionary impact of difference” (xii). This and other aspects of Hutcheon’s theory guide my interpretations of works by three contemporary artists working in Canada: Sybil Lamb’s novel I’ve Got a Time Bomb; Ursula Johnson’s (Mi’kmaq) three-part exhibition Mi’kwite’tmn (Do You Remember); and Kent Monkman’s (Cree and Irish) exhibition Shame and Prejudice: A Story of Resilience.
I argue that the presence of parodic elements in these artists’ works enables them to do two things: to claim spaces that enable recognition of their subject positions, and to critique an aspect of hegemonic norms in contemporary society. I read Lamb’s novel as a critique of the heteronormative gender binary via parody of the picaresque genre and of heteronormative discourse/language. Certain pieces in Monkman’s exhibition parody the epistemological and display strategies of traditional Eurocentric anthropological museums and archives, as can Johnson’s work; her sculptural-installations may also be read as parodying the traditions of Mi’kmaw basket-making. The work of both artists critiques colonial narratives that sought (and may still seek) to denigrate and/or erase Indigenous peoples; such narratives of cultural genocide were both tacitly and directly propagated by museums. I analyze these three artists’ works, considering key features of parody (ambiguity; irony and “double-voicedness”; trans-contextualization; and humour), and their effects (defamiliarization; ontological instability; complicity; and laughter). Parody challenges the post-structuralist emphasis on the “decoder,” (viewer/reader) reinstating the “encoder” (artist/author) as agent. Decoders recognize their complicity within the context of the hegemonic narrative, whether the heteronormative gender binary or colonialism, and may come to shift perception – as per Hutcheon’s “potentially revolutionary impact.”

This dissertation is a critical review of the discursive formation of Islamic art in the twentieth century and the continuing problems that the early categorization of this discipline carries. It deals with the impact of these problems on the conceptualization of another category, Persian art. The subject is expounded by three propositions. First, the category of Islamic art was initially a product of Orientalism formulated regardless of the indigenous/Islamic knowledge of art. Second, during the early period when art historians examined different theoretical dimensions for constructing an aesthetic of Islamic art in the West, they imposed a temporal framework on Islamic art in which excluded the non-traditional and contemporary art of Islamic countries. Third, after the Islamic Revolution in 1979, Iranian scholars eventually imposed academic authority over the discipline of Persian/Islamic art, they adopted the same inadequate methodologies that were initially used in some of the early studies on the art of the Muslims. These propositions are elaborated by examples from twentieth-century Iranian movements in painting, The Coffeehouse Painting and The School of Saqqakhaneh, and the incident of swapping Willem de Kooning’s painting Woman III with the dismembered manuscript of the Shahnama of Shah Tahmasp in 1994. The conceptualization of Islamic art as a discipline is also discussed in relation to the twentieth-century cultural context of Iran. The argument is divided into three chapters in relation to three important historical moments in the history of contemporary Iran: The Constitutional Revolution (1905-1911), the modernization of Iran (1925-1975), and the Islamic Revolution (1979-onward). The formation of the discourse of Islamic art is the fruit of nineteenth-century Orientalism. Out of this discourse, Persian art as a modern discourse addressing the visual culture of Pre-Islamic and Islamic Iran came into being. I claim that after the Islamic Revolution, Iranian academics demonstrate a theoretical loyalty to the early theorizations of Islamic/Persian art. By this token, visual signs are given a meta-signified in the narrative of Islamic art. The ontological definition of this meta-signified is subjected to the dominant ideology, which determines how different centers of meaning should come into being and disappear. In the post-Revolution academia, the center is construed as the transcendental signified. Such inherence resulted in a fallacy in the reading of the Persian side of Islamic art, to which I refer as the “signification fallacy.” The dissertation draws on the consequences of this fallacy in the critique of Islamic art.

This thesis examines how food, culture and identity are linked to the idea of "home." Through a reading of oral narratives produced on the YouTube channel "ShowMetheCurry," I investigate how presenters Anuja and Hetal "write back" from a diasporic space in Texas, to the YouTube global public, and how food and cuisine, even in the age of globalization can be problematic in terms of representation of identities, work and space. I explore how the YouTube videos operate as a heterotopia, as what is presented to the audience in this medium is an embedding of spaces. The space that is projected through "ShowMetheCurry," that of Anuja and Hetal's own home kitchen, is then projected and viewed within the audiences' own spaces, in various locations around the world. What connects these spaces is an interest in cooking, and a longing to satiate culinary nostalgia.

Research to date on social problem solving typically focuses on elementary school aged children. However, adolescents and young adults may experience more novel and emotionally complex social conflicts that require different skills to navigate them successfully. Previous research has highlighted executive function (EF) and emotion regulation as possible skills that help with social problem solving. The current study examined the potential relation between EF, emotion regulation, and social problem solving. The sample consisted of 174 participants with a mean age of 19.60 years. Results showed that the shifting component of EF was associated with being able to take different perspectives when coming up with a solution for a social conflict involving a romantic partner. Additionally, emotion regulation was associate with perspective taking in the overall social problem solving process with a romantic partner. These results suggest that both EF and emotion regulation are involved in the ability to take different perspectives during a social conflict in this age range.

Giardia lamblia is an intestinal parasite found globally in freshwater systems that is responsible for endemic outbreaks of infectious diarrhea. As a unicellular parasite that lacks mitochondria, a respiratory chain and lives in the anaerobic environment of its host's intestine, Giardia was assumed for decades to lack heme proteins. However, its genome encodes several putative heme proteins, including three with sequence similarity to the cytochrome b5 family, referred to as Giardia cytochromes b5 (gCYTb5). Recombinant expression of one of these genes (gCYTb5-I), results in a protein (17-kDa) that is isolated with noncovalently bound heme. Resonance Raman and UV-visible spectra of gCYTb5-I in oxidized and reduced states resemble those of microsomal cytochrome b5, while sequence alignment and homology modelling supports a structure in which a pair of invariant histidine residues act as axial ligands to the heme iron. The reduction potential of gCYTb5-I measured by cyclic voltammetry is -165 mV vs the standard hydrogen electrode and is relatively low compared to those of other family members. The amino- and carboxy-terminal sequences that flank the central heme-binding core of the gCYTb5 are highly charged and do not occur in other family members. An 11-kDa core gCYTb5-I variant lacking these flanking sequences was also able to bind heme; however, we observe very poor expression of this truncated protein as compared to the full-length protein.

This research explores the obstacles Jordan is facing regarding the sustainable treatment and reuse of wastewater in the agricultural sector. It assesses the technical, socio-cultural, and political aspects of decision-making around water and wastewater management in Jordan by focusing on a case study involving wastewater usage in the Jordan Valley. It includes a literature review and interviews with representatives of key stakeholders. While at one level wastewater treatment is a technical process with technological solutions, a nuanced understanding of the non-technical challenges facing the wastewater treatment sector in Jordan is necessary. These challenges are inherently embedded in and contextualized by a series of historical, complex and dynamic political and socio-cultural issues involving stakeholders at local and national levels. Only through an interdisciplinary approach with real stakeholder engagement will meaningful solutions to these challenges be developed and implemented, and at least a portion of Jordan's water needs be meaningfully addressed.

Soils play a crucial role in ecosystem functioning, for example, soil minerals provide important provisioning and regulate ecosystem services. This study used major soil oxides from the North American Soil Geochemical Landscapes Project (n=560) to assess elemental associations and infer soil minerals through exploratory data analysis and to determined quantitative soil mineralogy using a normative method, Analysis to Mineralogy (n=1170). Results showed elemental variability of oxides across the provinces of Canada and strong correlations occurred between elements indicative of soil mineral composition (e.g., Silicon and Aluminium). Principal component analysis inferred soil minerals from soil oxides trends on biplots and classified minerals, generally, as carbonates, silicates, and weathered secondary oxides. Spatial variability in minerals (quartz, plagioclase, potassium feldspar, chlorite, and muscovite) was related to the underlying bedrock geology. The use of Analysis to Mineralogy led to a reliable method of quantifying soil minerals at a large scale.

Cytokinins (CKs) are hormones that promote cell division. During the formation of tumors in the Ustilago maydis-Zea mays pathosystem, the levels of CKs are elevated. Although CK levels are increased, the origins of these CKs have not been determined and it is unclear as to whether they promote the formation of tumors. To determine this, we measured the CK levels, identified CK biosynthetic genes as well as CK signaling genes and measured the transcript levels during pathogenesis. By correlating the transcript levels to the CK levels, our results suggest that increased biosynthesis and signaling of CKs occur in both organisms. The increase in CK biosynthesis by the pathosystem could lead to an increase in CK signaling via CK translocation and promote tumor formation. Taken together, these suggest that CK biosynthesis, signaling and translocation play a significant role during the formation of tumors in the Ustilago maydis-Zea mays pathosystem.

ABSTRACT
Calving site selection and fidelity in a restored elk (Cervus elaphus) herd in Bancroft
Ontario, Canada.
Michael R. Allan
Parturition site selection by ungulates is believed to be influenced by forage abundance and concealment from predators. In 2011 and 2012, I used vaginal implant transmitters and movements to identify calving sites for 23 GPS collared elk (Cervus elaphus) from a restored herd. I tested the hypothesis that maternal elk used sites with higher forage and denser concealment compared to pre-calving sites at micro and macrohabitat levels. I detected no significant microhabitat differences from direct measurements of vegetation. At the macrohabitat scale, based on proximity of landcover classes, mean distances to hardwood forests was significantly less for calving (153 m) than pre-calving sites (198 m).
Site fidelity is hypothesized to offer security in terms of familiarity to an area. I tested the hypothesis that females demonstrated fidelity to their previous year's location during pre-partum, parturition, post partum, breeding and winter periods. Elk were more philopatric during parturition and post partum than during breeding. Compared to winter elk were more philopatric during pre-partum, parturition and post-partum periods. Expressed as distance between consecutive-year calving locations, site fidelity varied with 27% of females exhibiting high (<1 km), 18% moderate and 55% (>2.9 km) low fidelity.
I measured nearest-neighbour distances at calving time, exploring the hypothesis that females distance themselves from conspecifics. Elk increased the average distances
to collared conspecifics during parturition; however, sample sizes were small. This strategy might influence calving site selection.
Rapid movement prior to parturition, low site fidelity and spacing-out of females during parturition appear to be strategies to minimize predator risk and detection. Little evidence of selection for vegetation structure suggests this may not be limiting to these elk.
